Pyrolysis GC-MS was used to profile residual solids after drying aged whiskey samples. The samples in question were both 20 years old from the same unaged parent distillate but matured in the very different wood species of Quercus Robur and Quercus Alba. Fractionated pyrolysis chromatograms ...
Direct thermal desorption coupled with the Gas Chromatography–Mass Spectrometry (TDU–CIS4–GC–MS) technique applied to powdered milk was used as a novel approach for the characterization and quantification, as relative abundance, of volatile organic compounds (VOCs). The aim of this study was ...
